From 9ebe26cf7acf40391afb6caa4d38bb9cc83a27f0 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 10 Feb 2014 15:20:30 -0700 Subject: [PATCH] staging: comedi: usbduxfast: remove TRIG_TIMER from scan_begin_src Currently the (*do_cmdtest) indicates that TRIG_TIMER is a valid scan_begin_src but later this source is tested as -EINVAL. To simplify the code a bit just remove the TRIG_TIMER source.
